Serpent designer Billy Easton from USA, is part of a team of 5 designers, each with their own specialty. He is responsible for and very proud on this latest design of the Cobra SRX8, which he worked on for the past year.  Billy used the input from many Serpent drivers, teamdrivers and distributors, to create this brandnew 1/8 buggy. The focus is as always on performance, but we have paid a lot of attention to ease of use, and durability.  View also the Designer interview on our website.

Serpent as company started in 1980, and has over 30 years experience in developing, testing, designing and manufacturing radio controlled modelcars and is one of the longest existing rc brands in the World with 9 World Championship titles and countless European, American, Asian and national titles won by Serpent drivers !

Serpent Cobra SRX8; Full Details

The chassis cnc machined from 3mm thick aerospace type 7075 T6 aluminium and  comes hard anodised for durability.  The new shape is wider at the rear  to help the chassis roll and drag in rougher conditions. The kick-up angle is optimised to fit with the mating parts.  All holes in the chassis are countersunk.
The chassis features 2 large pockets, one is for the steel skid plate and one for  the  central skidplate.  There are 2 keyholes to center-fix the front and rear suspension brackets in place. The pocket for the flywheel is large enough to suit most commonly used starterwheels.
The sideguards mount to the bend chassis-sides from the inside with  pre-threaded holes in the chassis. The chassis offers good size surfaces for the downstops.

Rear skid plate
The cnc machined steel skid plate will protect the chassis at the rear end where it wears most. Its easily replacable by a new one, with just 4 screws. Optional ones in other materials to follow.

The  steeringblocks  are made of 7075 T6 aluminium and are anodised in black.  These steering blocks have been designed to allow you to change the Ackermann at the steering spindle as well as give us the optimal scrub offset in conjuction with the caster block. The bushings press into the blocks and reduce any unwanted play.

Chassis stiffeners
Extra long  chassis stiffeners, front and rear in composite material to offer the right flex and prevents the chassis to bend too much. Easy locking fastening system.

The composite sideguards help to keep debris out of the car, add rigidity to the chassis and support the body.  The sideguards are fixed to the chassis from the top in pre-threaded holes in the chassis. This way the screws are protected well and its easier to re-assembly when needed. The sideguards feature a pocket on the outside to allow mounting some felcron tape to guide / fix the body.

Steering system � servo saver
The dual  axis steeringsystem with integrated servo saver is mounted under an angle for less bumpsteer and a more direct steering feel.  The axis are made in light weight aluminium.
The new bellcrank accepts a bearing raced crossbar with zero slop. It  designed with the optimal Ackermann to  increase the cars driveability.  

Servo saver
These new servo saver parts not only have the new Ackermann, but also have a new internal servo saver design.  It incorporates a helix in order to guarantee the proper operating of the servo saver assembly. The servo saver spring is protected by a dense foam cover, to keep debris out.  The spring pre-tension clamp nut  can be locked in place to avoid turning loose.

The easy to use and durable radiotray is made as low as possible but in such way that all electronics fit in easy and well. Its features a seperate section in the front for the battery pack, to have the heavier part more front. The lid has 4 screws. Both servo�s fit in nicely with plenty servo-spacers to mount them on the right height. The chassis below the servo�s has lower pockets to allow mounting the servo�s very low. Ofcourse you need to think about chassisflex/torsion, so don�t mount them too low. The transponder, small or medium type, has a nice flush mounted holder included. The receiver box also has 4 small screws for easy and fast access. You can mount a standard switch, or use the supplied cover in case you use another solution. 2 decals are included to cover the battery and receiverbox.

High quality 2 piece dense foam  for perfect filtering ( use topquality  airfilter oil only ).  The  holder allows for easy assembly. On the front �top side the mount is attached to the center support with a spring wire, fixed with a bodyclip. The new rubber elbow  allows for good airflow and features wide grooves to apply tie-wraps.

The125cc  fuel tank is a complete new  design.   The spring and cap allow the pressure to be  more equal across the entire top of the cap, as well as the design of the cap has no flex .  The clunk has been enlarged so it will sit at the bottom of the tank and will not pop up or float at the bottom. While the drain section on the top has been improved where there is now a 4mm hole that will allow dirt and debris to escape and not clog. The fuel-tube clips now mount to the tank with screws so you wont have to worry about loosing them. The tank pull will enable  faster and more secure refuelling.   The tank has been re positioned so that its further away from the exhaust , which will prevent melting of the tank.  The kit includes  purpose made insert  to reduce the content if needed.  The tank mounts on 2 strong composite poles  with rubber grommets for flexible mounting and allow easy dis-assembly for checks and cleaning.

Driveshafts / transmission
The Serpent springsteel driveshaft are equal in length in front and rear and 1 of the central ones, which is easy for spares stocking.

Center diff mount
Durable center mounts with large size bearings  to mount the brake system and center diferential. A moulded brakedisk guider is mounted on the brackets.  The whole system is made as low as possible for CG reasons.  The sleek top-cover keeps dirt out and guides the 2 brake cams.

The SRX8 provides a conventional braking system with brake cams, steel disks and steel pads with effective pre-glued brakepads .

Differential cases
The strong moulded differential cases which contain the differential and supports the shocktowers.
The differential front and rear can be removed after taking out only 4 screws and removing the anti-roll bars, super-easy !

The diff housing has been completely re-designed to make way for evolution in diff technology.  The diff now has cavities designed specifically for closed cell foam. This foam will compensate for expansion of the oil, which will allow us to fill the diffs more full, keeping the gears fully engulfed in oil. The cavity where the gears rest has also been redesigned so that there is not low pressure zones outside of the gears. This will keep more oil on the gears even when spinning at high rpms. This in turn will keep the diff more consistent at low and high speeds as well as hot or cold .

Differential gears  28 / 14 / 44
The hardmetal 28T and 14T satellite gears have a  larger overall diameter,  to make sure they are more in oil, making the diff more consistent , smoother and stronger .  The steel 44T ring gear is lighter and has  a perfect match with the new 28T gear.  

Engine mount
Lightweight CNC machined engine mount in 7075 T6 aluminium with pre-threaded holes and large contact area with chassis, comes grey anodised .

Wingholder rear
The rear wing holder is a super durable and light one piece moulded unit . The set includes wing-spacers to put the wing under a range of angles.  

Wheel axles / hex / boots
The  durable Serpent springsteel wheelaxles are captured CVD style  and have rubber boots to protect the system and bearings against dirt and dust, so it will all last longer.  The wheel hex is a durable hard aluminium version which fits all popular wheels very well.  The pins in use are 3mm ones to increase durability.

The  new 15 dgr  c-hubs are made in 7075 T6 alminium and are anodised in black.  These open style very durable units allow enough space to allow for the maximum steering-angle and lalow space to mount the rubber dust  protectors on the CVD system.  As optional we offer 13 and 17 dgr alu c-hubs too.

The uprights are made of 7075 T6 aluminium with black anodizing and are universal ones to be used left and right .  The new uprights have the roll center adjustment in them with small inserts . Set screws are used to tighten down on the hinge pin to eliminate any unwanted play.  In the bottom part 2 threaded holes are made to allow for mounting  the optional brass weights of 15 gr each  for rough conditions.

Very durable and long moulded wishbones  front and rear.   The composite is chosen to have enough flex when needed.  The design has pockets in the top and bottom part of each arm  to mount the standard moulded insert plates, or the optional carbon fibre ones.   In that way you can choose the right arm flex for each condition.  Even different or no inserts front or rear and mixing moulded and carbon inserts is possible. The moulded inserts will stiffen the arms only a little, but keeps them cleaner. The carbon ones,  or mixed with moulded ones will stiffen  the arms a lot. Many options to try and apply.

The mudguards are offered in lightweight transparant polycarbonate  and can be left clear, be painted or skinned as prefered.

Suspension brackets
The suspension brackets are CNC machined in 7075 T6 aluminium and grey anodised. They key into the chassis for perfect fit.  The brackets have precision machined pockets to use inserts to alter the set-up.

Anti-roll bars
The anti-roll bar system is the best around. Precison made wire runs in ballraced adaptors on the front and rear diff case-plates.  Superfree and stabile.  The wire connects to a balljoint which is fitted with a pivotbal to the wishbone.   The works !

The front and rear shocktowers are durable 4.5mm carbon fibre units, CNC machined.

The effective 4-carbon shoe  race clutch is continued . It can be completely pre-assembled  and then be mounted to the engine. The system comes with a  light and small alumnium flywheel  and durable springsteel 13T clutch-housing .

Shock springs
Race shock springs which are pre-selected and paired. The shocksprings are grinded flat for perfect operation.

The shocks are a completely overhauled design.  Durable polished steel 3.5mm rods are used with hard anodised caps and threaded shock-bodies.  A new sealpack consist of machined bushings and new x-rings and is kept in place with a small inside clip.  The shockpistons are machined delrin units for best performance.  The shocks in the kit are membrame style, with emulsion type hardcoated caps and seals to be offered as option.    

Wing rear black
The new flat type rear wing is a very effective medium downforce unit with large sidewings.  The decalsheet offers sidewing decals to apply.  

The rear body mount has a rubber cushion in it. It allows the body mount to rotate front to rear in an impact or crash. This saves the body from breaking or tearing. The front one is a fixed type and is easy accessible.

Top quality shielded bearings with grease throughout the kit.

A new Avenger style  body is developed for the  SRX8 with medium level downforce.  Cab-forward style body with small fin on the roof for stability.  Nice flowing sides with small rear upward fins for rear downforce. Enough space to allow for airfilter, enggine head, carburetor and exhaust / exhaust adaptor. Top quality polycarbonate.   The body has nice trimlines for easy cutting. Same for the bodyholes. A masking sheet is included to assist with  paintjob preps.

Box / packing:
The Cobra SRX is supplied in a strong carton box with Serpent logo, which can be re-used for tyres or other equipment. The box is covered with a nice full color sleeve showing the car front and back.

New style manual in landscape orientation to have more space to explain all, and have correct layout for screen use as well.   Full color version with additional detailed views and notes, and also showing the hardware in real size on each page.  First batch will have a USB stick with the PDF, future batch will have also a printed one.
